SPECIFICATION Aforming part of Letters Patent No. 246,300, dated August 30, 1881.

Application iled February 2i, 188.1. (No model.)

To all whom it may concern:

Be it known that vL-HEINRY B. ESTES, of Lowell, county of Middlesex, State ot Massachusetts, have invented an Improvement in Spinning-Machines, of which the following description, in connection with the accompanying drawings, is a specification.

This invention relates to that class of spinning-machines known as speeders,7 and is an improvement; on the mechanism described in United States Patent Nm 228,809, dated J une 15, 1880, to which reference may be had.

In this my invention the upper end of the quill is permanentlybut loosely connected with the bow-flier in line with its nose or upper Hbear-img, connected with and extended above the yoke of the tlier, so thatithe lower end of the quill maybe readily turned or swung out laterallyfroin between the flier-arms, to permit gitndinally with relation to the quill to form 'a prolongation thereof 'when desired, and

loosely ,-conr'iected therewith, is a slide-rod, made as a b'it, which extends into and through the bohbi gend, emerging from the lower end of-the heb 1in, is made to en ter an axial socket in the 'upper endr oi' the shortened spindle. "When the lower end of the slide-rod is in the 'socket of the spindle the quill and spindle are locked or held togetherin line to permit the head or top of the spindle in engagement with the lower end-ofthe bohbin to rotate the vlatter, and at the same time raise and lower it as the spindle is raised and lowered by reason of its connection with the usual traverse-rail. In my. invention the parts which support the bobhin internally, and about which the bobbin is turned by the spindle, are connected with the ier, and always'rem ain so Without liability of becoming detached during dotng, and the bobbin may be quickly and easily doi'ed withoutvespecial care. As the operator applies a bobbin to the quill the upper end of the bobbin will act upon a collar ot' a bobbin-centering Y (lo-operating with 'this quill inside the bohbin, and movable lon- 1 device composed of a short sleeve and a connected ilange or head, which is joined with the upper end of the slide-rod by apin extended through a slot in the quill, and will more the slide-rod in the quill upward with the bobbin.

ln this way the operator, by grasping only the` bobbin, is enabled to lift the slide-rod abovev the npper end ofthe spindle, so that when the lower end of thebobbin is placed on the hea-d or top ot' the said spindle the lower end ot'- the slide-rod will come correnti y inte line with the slide1'od-receiving socket or opening in the top ot'- the spindle. I have provided the spindle with a holeor opening which intersects the lower end of the socket therein, which obviates theirapping the air below theend otb thc sliderod, which would preventthe prompt entrance of the slide-rod into the said socket.

Figure l represents, in elevation and partial section, a Hier and spindle embodying my invention, with the bobbin in section and the upper end of the spindle broken out to show the slide-rod entered therein to lock and hold the quill in line with the spindle, stillen the parts, and hold the 'bobbin firmly at the center of the iier` Fig. 2 is a partial side elevation ot' Fi g. l, showin g the quill and slide-rod turned out laterally from between the dier-arms in the position the qui-ll will occupy when doiing the bobbin, the quill being partially broken out to show the slide-rod, the bobbin-centering device 'being in section, one arm of theier being also broken away to show the tcp oi the spindle; and Fig.. '3 is a detail ot' the flier-nose and part of the yoke.

The spindle a will have its step in a traverse rail ot' usuel construction, and will be rota-ted in the usual way by means of the bevel-gear, having a keyl to enter the usual groove, c, in the spindle, the said gear b being so held that it rotated; The spindle a, instead of being ot' sufticieut length to extend nearly to the top of the bobbin d, is shortened and providedwith a boboin driving head, e, composed, as herein shown, of a sleeve, 2, a collar, 3, and a lug, 4,

2 ,A adecco at the side of the sleeve. The ends of theA bobbin d are chambered to t the sleeve or" this head e, and either end of the bobbin which may happen to be down when applied to the qnillf will reston the said collar 3.

I have shown the lug e as provided witha 'bobbin'holdiug lip, 6, which, after the lip has been inserted a little way into a longitudinal groove, 7, of the bobbin-head, the groove being shown most clearly and lettered only at the top of the bobbin in Fig. 1,) coince in line with a small annular groove, 5, so that the bobbin at that time seated on the collar 3 may be partially rotated by hand and cause the lip 6 to enter the said groove 5 and prevent the bobbin being lifted, unless it is again positively rotated on the said head by the operator, so as to permit the lip 6 to`come opposite the vertical slots in the bobbin. The lng 4, by its en gagement with the bobbin, rotates it positively in unison with the spindle. The bearing g for the flier will he held in the stationary flier-rail, with the gear h next below the said rail, and the said gear, driven by another bevel-gear, will rotate the flier, all in the usual manner. The Hier-arms i and presserj are ot' usual construe tion. The upper ends of the flier-arms are joined with a flier-yoke, l, having above it the usual hollow nose, m, which, besides serving as the top bearing for the flier, also permits the introduction of the roving into the opening 16 of the nose in the axis ot' rotation o' the flier. I have provided the under sides of this yoke with a projection, n, which is opened at one side in continuation of opening' L6, (see Fig. 3,) and close to the under side ofthe yoke I have provided this projection n with an annular groove, zr, to permit the roving led into the nose and below the yoke vto bc wrapped part of the way around the said projection, after which the roving is led' into the slot 18 in the yoke and diera-rm, down along the said arm, and out of the same onto the prcsserj.

Passing the roving about the projection n insures that all the 'twist pnt into the roving by the flier shall be put in between the said projection and the usual rolls (not shown) which deliver the roving to the iiier, and consequently the roving between the projection lnl and the bobbin will be kept uniform as to twist. This projection is herein shown asmadc available as the support for the quillf, which is shown as a hollow tube, slotted at one side, as at 19, for nearly its wliolc length, the connection between thc said quill and the projection n being', as herein shown, made ns a liinge-eonneetionviz., by means of a pin, j), (shown in dotted lines, Figs. l and 2,) extended through the crotched lower end of the projection n, and through an carat the upper cnd ot' thc quillf, the latter being free to turn out from and into position between the Hier-arms about the said pin or pivot p.

lThe slide-rodr, fitted, as herein shown, within the quill f, is connected by a pin or screw, t, with the centering device for the upper end of the bobbin, the said device being composed of a sleeve, 10, preferably beveled or made cone-shaped at its lower end, and having a head, 12, to come in contact with the upper end ofthe bobbin, as in Fig. '1. The guide and slide-rod are rotated by and in unison with the icr, and are always connected and in proper position with relation to each other to permit a. bobbin to be applied to or to be removed from the quill. It a bobbin, d, is to be applied, the slide-rod and quill will be turned out more or less from between the nier-arms, as in Fig. 2, the presser being preferably at the rear side ofthe ilier,) and the opera-tor Will grasp a bobbin and push it up along the slideroud until the hea-d of the bobbin meets the head ofthe centering device, when further upward movement of the bobbin will lift the slide-rod fr with it, retractin g the slide-rod into the quill f. The bobbin will be moved up ward-.until the lower end ol' the slide-rod has been lifted to a point above the head e of the f spindle a, when the operator will place the lower end ot' the bobbin upon the said head and partially rotate the bobbin until the driving-lug d enters one oi' the slots 7, of which there may be several in the bobbin, thus gaging the lug with and so as to drive the bobbin. Placing the end ol' the bobbin on the said head and permitting the bobbin to more downward insures the proper' and straight entrance ot' the lower end of the slide-rod into the socket s at the upper end of the head and spindle. The slide-rod will,being mader suiiicientl y heavyLcause its lower end to enter the said socket bythe action of gravity alone;

rlhe slide-rod should iit the socket s rather closely, to insure the greatest steadiness in rotationot' the spindle and tlier and keep the head of the spindle centrali It' the spindle be iitted rather closely to the said socket, the lat- -ter would act ns a dash-pot and the air would be trapped therein nnderthe descending sliderod. So to obvia'te this I have provided the IOO IOS

IIO

spindle with an. air-hole, fw, (shown in heavy f black lines, Fig. 1,) to permit the air to be forced out under the descending slide-rod.

)onnccting the quill positively with the upper portion ofthe iiier and the slide-rod positively with the quill and extending the sliderod directlyinto the spindle forms a very stili' and rrn support for the bobbin as it is rotatedby the spindle, and gencrallystiii'ens the entire apparatus to enable it"to move at high speed. i
